Most common wall sockets require 3 pin round or 3 square pin plugs.
It is recommended that should guests require the use of electricity whilst in areas where electricity is supplied, that one carries International travel adaptors suitable with the above requirements.

Whilst on Mobile safari and within many of the remotely located lodges and bush camps, permanent electricity is not available. Lodges and bush camps run on generator and solar power supplies, therefore using invertor systems to provide a 220v power supply to tents and main lounge areas. Guests are able to use these power supplies to charge camera batteries and smaller electrical goods, however note hair dryers, electrical shaving devices etc will not be possible.
It is highly recommended that all guests carry additional and spare batteries whilst on safari.
